In today's electronic commerce environment, many retailers have adopted the practice of providing discounts and promotional incentives to consumers. A prevalent method used is the manually-entered promotion code. With this approach, a pre-defined code string (usually an alpha-numeric character sequence between four and ten characters in length) is defined by the retailer to represent a particular discount (percentage or absolute dollar amount) and a set of criteria or rules for qualification (e.g., dates, stock-keeping units (SKUs), minimum total purchase amount, and the like) These codes are made available to consumers through a variety of communication channels, including e-mail, web sites, direct mail, other printed material, and so on. Consumers are prompted to enter the codes on the respective retailer's electronic commerce check-out page. The retailer's point of sale (POS) system checks the validity of the code and the consumer order against the qualification criteria associated with the code. If qualified, the retailer makes the appropriate adjustment to the price or other order adjustment (e.g., free product or service).
